| <background> |
| <p>cURL is a command line tool for transferring files with URL syntax, |
| supporting numerous protocols. |
| </p> |
| </background> |
| <description> |
| <p>Multiple vulnerabilities have been found in cURL:</p> |
| |
| <ul> |
| <li>When zlib is enabled, the amount of data sent to an application for |
| automatic decompression is not restricted (CVE-2010-0734). |
| </li> |
| <li>When performing GSSAPI authentication, credential delegation is |
| always used (CVE-2011-2192). |
| </li> |
| <li>When SSL is enabled, cURL improperly disables the OpenSSL workaround |
| to mitigate an information disclosure vulnerability in the SSL and TLS |
| protocols (CVE-2011-3389). |
| </li> |
| <li>libcurl does not properly verify file paths for escape control |
| characters in IMAP, POP3 or SMTP URLs (CVE-2012-0036). |
| </li> |
| </ul> |
| </description> |
| <impact type="normal"> |
| <p>A remote attacker could entice a user or automated process to open a |
| specially crafted file or URL using cURL, possibly resulting in the |
| remote execution of arbitrary code, a Denial of Service condition, |
| disclosure of sensitive information, or unwanted actions performed via |
| the IMAP, POP3 or SMTP protocols. Furthermore, remote servers may be able |
| to impersonate clients via GSSAPI requests. |
| </p> |
| </impact> |
| <workaround> |
| <p>There is no known workaround at this time.</p> |
| </workaround> |
| <resolution> |
| <p>All cURL users should upgrade to the latest version:</p> |
| |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-misc/curl-7.24.0" |
| </code> |
| |
